274V - it's 38 7.2V batteries in series.


Isn't that 228 1.2V cells in series and 273.6V?


:-P

It's packaged as 38 7.2V packs no doubt made of 6 1.2V tagged cells each.

And you know damn well it's only a *nominal* 1.2V per cell, so it's probably
ranging from 1V/cell when discharged but off load (228V) to a max of
1.78V/cell when charging, at typical temperatures (405.84V)

In a crash situation, which is where we came from,presumably it would not be
charging, hence the upper limit would be more likely to be 1.4V/cell, i.e.
319.2V.

But anything from 228V right up to 406V in realistic situations should be
treated with the same level of safety measures, so it's a bit immaterial...
